Show affiliationsA method to produce novel polymer supported nickel nanowires, which are asymmetric (or anisotropic) in shape and function, using an alumina membrane as a template is presented. This paper reports a step-edge like fabrication technique using anodized alumina membranes. First the membrane is treated with fluorosilanes to make the surface completely hydrophobic. It is then cleaved to expose the freshly prepared alumina edges, which are hydrophilic. These freshly cleaved hydrophilic edges are used as templates for the deposition of polyelectrolyte multilayers and nickel. We selectively deposit polyelectrolyte multilayers on those hydrophilic edges. Then the electroless deposition of nickel is used to create nickel nanowires. After dissolving the membranes, we obtain nanostructures which are asymmetric in shape and function.
